injectors plugged? any codes being displayed? you said the fuel pump is operating correctly? some have had to replace fuel pumps from what you have described. maybe fuel filter is partly plugged as well.

check the T-bap harness, clean the T-bap sensor, and remove and clean the throttle body. New plugs never hurt also.
